(KMOV.com) - Senator Roy Blunt said he's concerned about serious claims made by an employee at a Wentzville company with a lucrative government contract and he vows to get to the bottom of it.

Hundreds of employees were hired to process healthcare applications for the Affordable Care Act, known as Obamacare.

Now former employees told News 4 they were bored and desperate for things to do at the office.

Paula Bujewski spent two months at the end of 2013 working for a company called Cognosante, which worked under the same roof as Serco at a massive office building in Wentzville.

“What I deducted from the time I was there is that somebody has figured out how to make a lot of money off this deal to do nothing,” said Bujewski.

She said her office worked in conjunction with Serco to process healthcare applications and that most days were spent doing a whole lot of nothing.

“Our supervisor said if we process one or two of these a month we have done our job … it was a lot of money to be spent on that little bit of nothing,” said Bujewski.

She told News 4 she will never forget an office visit from Serco management and the Center for Medicare and Medicaid Services, which oversees Serco's $1.2 billion contract.

“They would tell us to come in dress professionally and act like we were working (to pretend) … pull our chairs in to our cubicles and yes look at the screen as if we were reading things with fingers on the keyboard and yes that's exactly what we did,” said Bujewski.
